Legendary sound

Infinity's Kappa Series 682.11i 5"x7"/6"x8" speakers continue in the tradition of this legendary line of speakers, offering rugged construction and impressive sound quality. Once installed, these speakes will bring out every nuance and detail in your favorite music tracks, making time spent in your car seem more like a concert than a commute.

Large soft dome tweeters

If you're looking for natural-sounding high frequencies, Infinity uses edge-driven 1" soft dome tweeters in this system. The "edge-driven" design creates a larger tweeter that handles more power and delivers smooth response way down into midrange frequencies not covered by smaller "W"-shaped domes. You'll hear a more clearly defined soundstage where you can picture the placement of every instrument.

Infinity's UniPivot design allows you to aim each tweeter toward your ears, so you enjoy excellent stereo imaging even if the speakers are mounted way down low in your doors. Each tweeter also features a level control switch so you can boost the brightness to your taste.

Glass fiber woofer with Plus One+ technology

If you like bass, the Kappa glass fiber woofer holds its shape when the power's cranked up, so you still get punchy and defined bass. Glass fiber weighs less than traditional materials, so you don't need a ton of power to drive this woofer. Infinity's Plus One+ woofer technology extends the cone right up to the edge of the basket, giving you more surface area than with most comparable speakers. A bigger cone means more bass to complement the superior high-frequency response.

Great for any system

These 2-ohm speakers are sensitive enough that you can power them with an aftermarket stereo, but you'll get your best results feeding them plenty of power from an outboard amp — up to 100 watts RMS. Grilles are not included — factory grilles are appropriate for most installations.

Why replace your car's original speakers?

The speakers that originally came in your car were made from inexpensive materials, designed to create acceptable sound at the lowest possible cost to the manufacturer. If you love music, you deserve better. Name-brand aftermarket speakers deliver fuller, richer sound with considerably more detail and nuance, and they're capable of playing louder and cleaner than factory speakers. Connect new speakers to your factory radio and you'll get the best possible sound from your dealer-equipped system. Pair them up with a new car stereo for a level of enjoyment that can rival a high-fidelity home audio experience.

Product Research

Features

Plus One Woofer Cones: The Plus One speaker cones offer
more surface area than other speakers that fit in the same size opening. This
is accomplished by using a new basket design and hi-roll surround. The result
is greater bass output and a significant increase in efficiency.

Formed Glass Fiber Woofer Cones: This formed glass fiber
material is very light and extremely stiff, minimizing cone flex. This results
in very low distortion and improved clarity.

iCGM frames: The Kappa series speaker baskets are made of
composite Injected Carbon Glass Matrix (iCGM). iCGM is lighter and stronger than
stamped steel; it retains its shape, even when mounted on uneven surfaces (common
in car mounting locations), plus offers exceptional damping of any resonances.

Edge Driven Dome Tweeters: Each speaker has a 1"
Edge-driven textile soft dome tweeter. An edge-driven tweeter has better dispersion
characteristics and allows for a lower crossover frequency than typical tweeters
of the same size, which improves imaging. The result is improved vocals and
musical clarity. The tweeter also has an adjustable output level, +0 dB (flat)
and +3 dB.

UniPivot Tweeter: The tweeter is angled and can be rotated
about 315° after installation. This allows you to direct the tweeters toward the
listeners, very useful for speakers mounted low in a door.

High-Output Design: The high output 2-ohm voice coil design
compensates for the high in-line resistance of small gauge factory wiring and
extracts every watt from factory receivers, increasing overall system output and
efficiency (relative to 4 ohm speakers). The speaker's 2.0-ohm impedance combined
with the impedance of your speaker wire provides a true 4-ohm load to your connected
headunit or amplifier. The speakers also benefit from increased power when you upgrade
the wire and add aftermarket amplifiers, designed to power a 2-ohm load.

Size: These speakers fit many 5x7 and 6x8 applications.

Terminals: The input terminals are gold-plated set screws that
will accept up to 12 gauge bare wire.

Power Handling: Although Infinity lists the RMS power handling
as 100 watts, they also list the recommended power range as 5-150 watts RMS. We've
opted to list the more conservative 100 watt RMS figure on the specifications page.

Excellent Upgrade

Merry Christmas to me! Purchased these as a BOGO special for cyber Monday special because I needed 4 speakers for 4 doors. Installed these in my 2006 F-150 Reg Cab. Big difference over factory. Radio is great but CD playback is excellent! But looking to install a amp and a new double din to finish my full upgrade. I can hear lows and highs very clearly, base is good but once I get the amp installed should bring out the full potential in the speakers. Crutchfield says it wouldn't fit my vehicle without some custom modification, stated the tweeter is too high but it installed without any issues in all four doors without any modification. Excellent Upgrade. PS. Customer Service was great also!

Great Factory Replacement

Just installed these in my 2011 Ford Escape Limited with premium sound package. Great replacement for factory door speakers. Now I have richer mids and lows are a little better. I was originally considering the Rockford Fosgate Punch, but a Crutchfield Rep advised me I would be happier with speakers with a higher dB, in this case 94 dB, since I didn't plan on replacing anything but the door speakers. After seeing some other reviews, I really want to upgrade my head unit and factory wiring to really make these speakers sound like they should. I am happy with the result.

Great Speakers

Bought these on a BOGO special because I intended to spend about $200.00 total on the four speakers which meant I was going to get lower quality speakers. I paid 179.00 for the first pair and received the second pair free. Installing them in my 2000 Ford F-150 Super Cab was very easy. I Googled how to remove the door panels and was surprised how easy that was. I received the adapters to hook these to the factory wiring harness which made the installation very easy as well. The only thing I had to do was cut off the spade connectors since the Infinity speakers use a screw in wire connector. After I finished installing the new head unit I was ready to try out the new system. I paired these speakers with a Pioneer DEH-X6700BT head unit which is the exact same unit I put in my 1957 Porsche Speedster.

I was very impressed with the sound quality from these speakers. I expected good sound from the Infinity speakers and they delivered. The bass is decent for a 5X7 speaker and the highs are very crisp which I like. I can turn these up to a decent volume without distorting them which makes listening to my favorite songs really nice. These are definitely not component speakers but neither did I buy these to be that. I bought these to be replacements for my factory in-door speakers and for that purpose they are performing better than expected.

I would recommend these to anyone looking for a very nice replacement speaker for their poor performing factory speakers.

Good speakers for the money

Installed 2 pair of these in my 2012 Ford Escape Limited with SYNC system. The speakers have good mid-range and sound better than the flimsy factory speakers. I think these will really shine with additional amplifier power though. The factory system just doesn't do them justice. This was the first step in the plan to upgrade the entire system and hopefully the Infinity's will really slam with some decent power.

Pros:Easy to install. Excellent build quality. I like the screw down terminals for the wires. A nice feature is that you can rotate the tweeter to a more desirable angle also. The sound is good but will most likely be a lot better with added power.

Cons:Really need a power amp or a decent head unit to reach their full potential.

Great Sound!

I just installed 4 of these in my 2013 Ford Taurus (1 in each door) and what a difference! The factory speakers had muddy bass and no clear high end. By contrast, the Infinity Kappa's produce clear, crisp sounds throughout the entire range of what the factory HU can provide. Replacing the factory speakers with nearly any 1/2-way decent product will make an improvement, but these Infinity's knocked it out of the park - and the ball still hasn't landed! The Ford radio has a 3-channel equalizer (low, mid, high). With the factory speakers there was no good setting, just varying degrees of mediocre. By contrast, I now have the low set to neutral (neither adding nor subtracting), the mid set to +1, and the high set to +2. I also have the balance & fade set slightly to the back and right. I still plan to install amps and a DSP as these speakers will benefit from additional power and a better signal.

Pros:Excellent sound; the set-screw wire connectors are a very nice touch; the bottom mount adapter rings allow the Kappa's to match the thickness of the factory speakers; perfect fit!

Excellent replacement for mustang

Replaced the factory door speakers on 2014 mustang with shaker and navigation. Had to get different mounts. I got the mounts from the Ford dealership. Mounts are pretty cheap. Just call them up, tell them what you're doing and they know exactly what you need. The new sound from these speakers will be lots better than the oem. Louder, clearer, you'll feel like you're in a concert hall. They work great with the stock door subs. The oem door speakers are 2 ohm as are these Infinity's. The rears are 3 ohm. I measured them with a fluke meter. The replacement mounts, you'll have to cut out some of the holding tabs with some dykes and use slightly longer screws. I have a pair of infiniti reference on back order for the rear deck.

Former Infinity lover

Written By LoverofgreatQA, Fort Wayne, IN on Tuesday, July 08, 2014

I dunno, maybe it boils down to personal preference, but these speakers in my mind fall way short of Infinity's older line of speakers. I had 4 (5x7's) of Infinity's old titanium dome tweeter aluminum woofer design speakers, and they produced way better mids and highs than these do. These speakers to me, sound like factory no tweet speakers just amplified. There is no crispness to the highs, at all. You might as well not have any tweeters. Like I said, it might boil down to personal preference, but soft tweeters do not sound good to me, especially when you pair with a good pair of sub-woofers and amp. You need some good quality highs that are loud and crisp to balance some good bass. I have two of Infinity's top of the line subs that I am now trying to find a replacement for, because their subs stink now as well. They sounded good for 6 months, but now they are blown and sound like crap. Sad to say, Infinity's older aluminum coned subs were way better too. I had them for 6 years and they always sounded the same, awesome! Their subs are crap now too. I loved my Kenwood deck, with my Infinity speakers, and subs, but they redesigned and went totally downhill. I still have my old pair of Infinity 5x7's in my front doors because they sounded too good to get rid of. Now I thought about replacing them, but no one even makes a speaker as good with a titanium tweeter. This is a huge step back if you ask me, come on get it together car audio manufacturers!

Pros:Fit great, look great

Cons:Lackluster sound, no brightness to the highs. Good quality bass will drown these things out.

The difference is night and day

I installed these in my 2009 Ford F -150 Supercab, both front and back doors. Over the past few months I have researched many different speakers and had asked a lot of questions of the advisors at Crutchfield. I finally decided on these speakers when they went on sale, but after I installed them, I would have paid twice the price. Eventually I intend to upgrade the entire system, having talked with an advisor I started with the speakers, I can't believe the difference in quality of sound that this one upgrade has made. From rich bass to astonishingly clear high range all without flattening out as the volume increases, these speakers deliver, I cannot say enough good things about them. Along with their wide range of knowledge about all things high fidelity, Crutchfield's installation guide made the job of swapping the factory speakers for the upgrades so easy, it took me less than two hours. Between Infinity's top quality products and Crutchfield's knowledgeable and friendly staff, there is no reason why you have to suffer with inferior car audio. I can't wait to get the rest of the system upgraded.

2006 Ford Mustang GT

I'm very happy with the sound of these speakers. I replace the two in the door and the two in the rear deck. Much better highs and lows than stock.

Pros:They do fit in the front door but you have to cut out the plastic alignments tabs for the stock speakers. I used a dremel and cut them out in less than a minute. All the screw holes lined up as well.

Excellent sound for stock radio

I installed these in a 2012 F-150. They were direct fit replacements for stock. I used the treble boost and replaced all four doors at the same time. I really like the sync hands free calling so I elected not to replace my HU. I think the sound is really good for not using amplifiers or any other signal processing. I do plan to replace the tweeters in the "a-pillars" in the future and I think this will help as well. Be sure to purchase banana connectors for the screw in terminals as the OEM adapters sent by Crutchfield are spade connectors. I just cut them off and added the banana connectors. For as simple a process as this was, I think the sound improvement for the money is well spent!

Sounds great!

Installed these in my 2013 F150 in the front - they sound great. I plan on replacing the rear speakers I bought with this pair because they sound superior. Look great, sound great, and easy to install, what more can you ask for?

Big improvement over the stock factory speakers!

The factory speakers in my 2013 Ford Edge sounded terrible. The Infinity Kappa 682.11cf made the factory system sound much better. Using the Bojo Trim Panel Tools helped remove the door panels, so I recommend them as well.

Crutchfield excellence!

Not only was the Crutchfield website able to pick the perfect speakers to fit my 2003 F-150 but the installation instructions made the install quick and easy. WOW! What an improvement over the factory speakers.

Pros:Having the Crutchfield experts help with selection and installation.

Infinity 5x7 Kappa

Written By The Ace of Basd, Bel Air, MD on Friday, April 25, 2014

Putting 5x7 coax in the stock location of a ford van. Running 50-70watts to them off a new Alpine f300 and a Kenwood double din with Xm. I tried the Polk dbs, the Kenwood Excelon and the Jl audio but it wasn't until I found the Kappas was I able to seamlessly meet the alpine Type R 12" sub I had in the back. The Kappas go low enough and really kick so that it feels like I have all my bass in front of me. And the swivel tweeter allowed me to play with different positions until I finally got my soundstage up on top the dash instead of sounding like it was coming from the sides like the other speakers. They really are a quality product with a lot of versatility and great sound. I liken them to a set of $400 Boston Acoustic components I used to have. But those needed 300 watts and the infinitys only need 75.

Infinity Kappa 5x7s

Written By Raptor Nine, Fort Collins, CO on Wednesday, April 02, 2014

Excellent speakers. I have these installed in an '03 Ford Ranger Super Cab and they rock! I listen to all genres of music and am pleased to say these are the best speakers I've owned. The highs are very clear and do not muddy until volume is well beyond a safe volume. The mids are well delivered for not being externally amplified. I only have a KDC-BT955HD head unit powering them. The lows leave something to be desired as with all unamplified speakers. I have them rounded out with an 8" JL Audio W3V3 subwoofer in a factory sealed box powered by an Alpine MRP-500 and the combination is perfect. Very highly recommended.

Infinity good sound without amp

Speakers are very nice out of the box. It's kind of confusing with the adapter plates on the speakers, your not sure if they stay on or take them off because os the thickness of the originals. I chose to take them off. I did have to go out and buy a 5.5 mm socket for the speaker removal and install. I bought two sets for the front and back. Had to send one set back due to one speaker stopped working. Crutchfield is sending me another set. After the install of the front, wow what a difference between the front and the rear. Can't wait to install the rears when they come in. I am thinking of adding an amp if all goes well to boost the speakers as they should be heard. Be careful tightening the screws for the speaker wires. You have to cut the adapters that they provide to use on these speakers.

Pros:Great sound out of these speakers even without an amplifier

Cons:A little more depth for the install with these speakers in your ford f-150

WOW these Kappas ROCK!!!

The sound from the factory stereo system in my 2012 Ford Expedition EL was pathetic. So I spoke with Cooper at Crutchfield and I told him, "let's do the speakers first". He expressed some concerns about going with the 2 ohm Kappa speakers without an amplifier, but I assured him I would be adding an amp in a few months, and that it would be OK for a while. So I had the Kappa speakers installed, and I was very unhappy with the new sound. So 24 hours later, I installed an Alpine MRP-F450 amplifier that I bought from Crutchfield a few years ago. At 100W RMS x 4 @ 2 ohms, it was a PERFECT spec match for the 100W RMS 2 ohm Kappa speakers. Now it was time for a new sound check...and WOW!!!! I could not believe it was the same Kappa speakers. At both low and high volumes, the sound is so perfectly clear. And when you turn it up, oh boy. Real loud! I will be calling Cooper in a few months to order a double-din headunit that will retain my Ford Sync functions. Or heck maybe I will do it tomorrow!

Don't try this at home

Written By Redneck Bob, The South on Sunday, November 03, 2013

I put these in my F350 and they sounded decent amped, then I completely dynamatted both doors and they sounded really good. The only thing missing was a nice, high sound stage and good imaging. The speakers in my truck are about knee height so it's tough to bring the sound up. I was gonna upgrade to a component set of these, but those run about $300! I decided to try something stupid and cheap instead. I pulled the stickers off the back of these, cut the little tweeter wire, pulled the tweeter off, and wired it back up with an extra 4 feet to play with. The tweeter wire was through a hole in the center of the speaker and the tweeter was just glued on, so it was a pretty simple job. I put the tweeters on my dash at the bottom corners of my windshield. I honestly thought it would sound terrible without a proper crossover, but it had the same good quality as before.The tweets were a little loud (closer to my head) so I just pushed the little -3dB button and they fell right in line. After testing some locations and angles, I now have a broad sound stage across my dash with the same great Infinity sound quality as always. You would be lucky to find a set of components that sound this good for less than $250. I say these are excellent speakers for the money. I am amazed that they sound so good even after what I did to them.

Pros:Sound quality is very good for the price, they separate the instruments well, don't have harshness, can be turned into "components" by a redneck and sound even better, don't cause listening fatigue

Cons:The voice range mid can get a bit peaky as is common for 5x7 , they need dynamat to stop resonance in some vehicles, can't be bridged on most 4 channel amps because of the 2 ohm impedence

Great Upgrade

I own a 2012 F=150 Super Crew, Replaced all 4 factory what they call speakers with these Infiniti's. AWESOME!! The sound is so much more crisp and clear, the low end isn't the greatest, but for a 6x8 you can't expect the world to change, but it's still a great upgrade. Also, when I received my speakers, one of the tweeters were broken, I called Crutchfield, they are wonderfully great! Within 5 minutes they had a replacement on it's way and completely hassle free. Thanks Crutchfield!!

Long term test

Written By Rex, Arkansas on Thursday, October 24, 2013

This is a long term review of these speakers from 4 years ago. They still had the glass woofer material and 2 ohm impedance but the tweeter was a metal dome instead of textile. I recently replaced the 10 year old infinity kappas with these 4 year old ones in my 2000 F350 with an amp. They still sound as good as when I bought them. They are so powerful that I had to dynamat all inside my doors because my door panel was bouncing on drum kicks. I added a sub and turned my high pass filter on these all the way up (120Hz), but they still put out a lot of bass. I got to listen to this new model and the new tweeter balances them out better, the sound is more natural and smooth. Infinity is great about giving you a good quality sound, like a home theater system. It sounds like my BMW stereo did except it's in a loud old farm truck, and I'm only running 3 speakers versus 11 in the BMW...

Pros:Tough, sound ok with no amp, awesome with an amp, powerful enough to run without a sub and be decent

Fantastic speaker!

Was looking for something to take my Shaker 500 sound out of the stone ages. Sound was very muddy. Always liked Infinity solutions so thought I would give these a shot. WOW what a difference they made!!! I now have great highs and mids and even increased the bass quality quite a bit. I have and will continue to recommend these to anyone!

Pros:Direct fit for Mustang 5x7 speakers in doors and rear deck, Drastically improved the sound quality, and can be used if I decide to go with custom amps down the road.

Perfect Ford Edge factory speaker upgrade

These Infinity Kappa 682.11cf are the perfect fit for most Ford Vehicles including the Edge. They sound amazing compared to the factory speakers and will sound even better with an aftermarket amplifier! Highly Recommended!

Fantastic replacement for stock F-150 speakers

I have a 2011 F-150 with Sync and wasnt sure whether to replace the speakers and add an amp later, or go with a helix or other system to optimize the sound from the stock system. I chose to start with these speakers, and it didn't disappoint. The muddy sound is gone, replaced by crisp smooth sound across the range! Next step: amp. But for now I am very about investing in these speakers.

Pros:Excellent sound across the audio spectrum, suprisingly good even in the bass range. Highly recommended.

Cons:None really. The speakers live up to my expectations. Instructions could be better for putting in the foam at the backside of the speaker, but thats not a big deal at all to me.

Excellent product!

Nice easy fit , as usual with Crutchfield's recommendation. The sound I wonderful in my Mustang but unfortunately now I MUST replace the front speakers to balance out the prefect rear sound.

Pros:Well built, easy fit, great sound! A huge upgrade from the OEM speakers.

Cons:None yet. You will have to change/alter how the speaker wires hook up to this speaker since they don't have spade end terminals - they have hole inserts with screws to clamp down the wire. No big deal!

2011 F150 Crew Cab

It's sad that you have to replace speakers in a $40,000 truck but we own 2 GM vehicles which made listening to these Ford made in China paper speakers unbearable so on to review I was told by Crutchfield not to buy these speakers if I was not going to amp them which I plan to do later and I always trust and listen to the Crutchfield reps but I have been checking on 6x8 speakers for over a year and had to buy these Infinitys and they are awesome and can't wait to amp them I put 4 in my crew cab and can't understand the people saying they don't have any bass compared to factory speakers they are so clear and have great mid bass with no amp I didn't increase tweeter db button, sorry Crutchfield but I promise I will amp them.

Nice!

Installed fronts in my Mazda 3 during my lunch hour today. WOW, huge difference. Another set on order for the rear doors. Man the stock speakers are junk! :) Wow, Wow, Wow!!! Goes nice with my new Sony head, now to save up for the AMP and Dynamat and the little 3 will be rocking to RUSH on the USB stick twentyfour-seven :)

F150 FX2

Sound quality is excellent when compared to factory speakers. These don't have quite the amount of bass as the factory speakers running off just the factory HU, but the quality of sound is 10x better than with factory. Maybe they need more time to "break-in" for some of the lower notes? Future plans are to run an amp to these to boost their sound. Going to install a small sub to take care of the lower notes.

Pros:Great Mids and Highs
Easy to Install

Cons:Need to run these with an Amp to take full advantage of their capabilities

2012 F150 FX4 SCREW

Installed 4 of these in my f150, one in each door. I find that these speakers needed a bit of a break in time. Bass is really good, they go pretty low for their size (6X8 in all 4 doors). Highs are nice, and have an adjustable tweeter (flat, or +3 dB). excellent upgrade from stock speakers. Running off stock head unit. Adding a 4 channel amp today to give them some extra juice. So far, so good.

Oooooo yes

If you are looking for a 6x8 speaker that really rocks then buy these speakers. I am never happy truly satisfied and can normally find the smallest thing in a speaker to complain about but not with these. I have them connected to Rockford PBR 300 and they are thumping. Deep bass and solid highs . I promise you if you buy these speakers and power them right you will not be disappointed.

Major Improvement!!

I installed these 6x8's in the front door of my 2013 Mustang GT. First off, they are a drastic improvement over the factory speakers (which sound as if the music is coming from inside a cardboard box). The highs are crisp and clear and the sound from the tweeters is made even better with the ability to swivel the tweeter head for improved imaging. The mid-range is also very clear. The speakers provide great sound at any volume with a variety of music genres. I can not speak to the bass level of these speakers as the factory Shaker 500 system splits the bass notes to the subwoofers mounted in the front doors. To Crutchfield's credit they did not provide fitment recommendations in the front door of the 2013 Mustang, and once I took the door panel off I could see why. However with a drill and a small drill bit I was still able to mount these speakers securely using the three factory mounting screws.

Pros:Amazing highs with great clarity. Well built. Swiveling tweeter for better imaging. Tweeter strength adjustability using the button on the front of the tweeter.

Excellent Speakers

I've always been a fan of Infinity, but this is the first of their Kappa line that I've purchased. I normally use their "reference" line of speakers. These are definitely a step up from the reference series, and also a step up from most other speakers on the market.

The clarity of these particular speakers challenges even Focal speakers in my opinion. Also, they go low enough to present the bass in any music, though not to the point of thumping dubstep. The imagining is really awesome on these things, especially with well-recorded tracks. Listening to a good recording of almost any Jazz piece really shows the detail in your music.

The only thing I've noticed that I don't like is it sounds like the bass is emanating from the floor with these. It is probably just my car though... but it's still worth mentioning. While listening to a Miles Davis piece, the trumpets and sax were extremely clear, and the imagining was absolutely awesome. However, the lower jazz bass had less clear imaging, and sounded to be coming from beneath me. Despite that, it was still very clear on the bass, it just was harder to place in the sound stage.

Like I said, this is probably because of my car and how the sound resonates inside of it. Other than that (Very very minor tidbit) these things are outstanding.

Pros:Awesome imaging, extremely clean and clear sound. Very detailed. They go low... 40hz is a reasonable rating. And they stay clean in the basses.

Cons:Some bass instruments have 'bleh' and average imaging... possibly do to the resonance of my car.

Product reviews from the Crutchfield Labs

Extremely accurate and efficient!

Written by Cooper, Advisor,
on 2/18/2014 11:39:00 AM

I helped my best friend, a fellow advisor named Eli, install a pair of Infinity Kappas into his F-150. I was extremely impressed with the tight bass response along with the crystal clear mids and highs these were able to produce.

We used a Sound Ordnance M-4075 to power these as they do need more power than what a head-unit can produce. We tested bluegrass, rap, country, and rock music tracks once they were installed, and these speakers delivered amazing dynamics. After hearing them, I think these speakers are the best for your money, no doubt about it.
